Peel and fillet the oranges thickly. Put in a terrine form. Heat the lemon juice, sugar, campari and wine, dissolve the soaked gelatine in it, pour over oranges. Chill for at least 3 hours.
Cinnamon sabayon or a mousse goes well with it, e.g. my mocha mousse or just half-whipped cream or a creamy ice cream.
